The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...
Background and purpose: Some problems such as filtration, centrifugation, and turbidity in effluent has limited the application of activated carbon and many nano-sized adsorbents. The magnetization of adsorbents using magnetic nano-crystals (MNCs) is a useful approach to overcome these problems. In the present study, magnetic activated carbon was synthesized (since it is separated fast and easi...
Synthetic dyes, azo dye in particular, are widely found in the effluents from textile industries. The persistence and toxicity of these compounds cause adverse impact in the receiving streams. A mixture of isolated cultures, from domestic sewage treatment plant was found to decolourize reactive azo dyes, Red RB, Blue M2B and Yellow, efficiently in the absence of added external nitrogen source. ...
background: recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. reactive dyes are widely used in textile industry. advanced oxidation processes are one of the cost-effective methods for the removal of these dyes. the main aims of this study were determining the feasibility of...
